2results about How to "Improve oxygen production efficiency" patented technology

The invention discloses a molecular film type automotive nitrogen and oxygen separation device which comprises a turbocharger, a nitrogen and oxygen separator, a gas inlet valve, a gas outlet valve, a negative pressure pump and an electric control throttling valve. The turbocharger is driven by a turbine in an automobile turbocharger, so that the air is compressed to be conveyed to two paths of the nitrogen and oxygen separation device, the nitrogen and oxygen separation device can separate oxygen from the air, the air with high oxygen content is output, and the air is supplied to an engine for use through the gas outlet valve. The two paths of the nitrogen and oxygen separation device work alternately, when the temperature of the two paths of the nitrogen and oxygen separation device is too high to influence oxygen production efficiency, a main air inlet pipeline is opened to provide air normally by controlling the opening degree of the electric control throttling valve, and thus the phenomena of gas circuit plugging and engine stalling are avoided. According to the automotive nitrogen and oxygen separation device, the two branch paths work alternately, high concentration oxygen can be supplied to the engine continuously so that fuel can burn and act, and the burning utilization rate of the fuel is improved.

This utility model relates to the technical field of oxygen generation equipment, and discloses a molecular sieve oxygen generation device, including a protective shell. A frame is fixedly arranged around the inner surface of the protective shell. A filter structure is fixedly arranged at the lower front edge of the inner wall of the frame. The filter structure includes a blower. An advanced air filter is fixedly arranged at one edge of the upper end face of the blower. A connecting valve is fixedly arranged at the output end of the advanced air filter. A molecular sieve structure is fixedly connected to the output end of the connecting valve. The molecular sieve structure includes a molecular sieve tower. In this utility model, through the arrangement of a layered molecular sieve filling structure and a gas distribution plate, the layered molecular sieve filling structure consists of molecular sieve layers arranged sequentially from top to bottom. A gas distribution plate is arranged between adjacent molecular sieve layers. The ventilation holes in the gas distribution plate allow the gas to be evenly distributed in the molecular sieve layers, thereby improving the oxygen generation efficiency.
